BYRON A. BROOKS, OF BROOKLYN, NEW YORK.

.. TYPE-WRITER.

SPECIFICATION forming part of Letters Patent No. 379,095, dated March 6,1888,

Application filed December 24, 1886. Serial No. 222.496. (N0 model.)

To all whom it may concern:

Be it known that I, BYRON A. BRooKs, a citizen of the United States,residing in Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Type-\Vriters, of whichthe following is a description in such full, clear, concise, and exactterms as to enable any one skilled in the art to which. my inventionbelongs to make and use the same, reference being had to theaccompanying drawing, making part of this specification, and to theletters and figures of reference marked thereon.

My present invention relates to type-writers and the means of inking theprinting-typesv thereof; and it consists of a movablc'inkingpad or rollwhich is held against or pressed upon or rolled over the face of suchprintingtype, and is then moved out of the way to permit the types toprint upon the platen.

The drawing illustrates a side elevation of parts of a type-writingmachine, including an inking device embodying the principles ofmyinvention,printing-types,and a platen. Other parts of the machine arebroken away or omitted.

The following is a brief description of the drawing:

O are a series of bell-crank levers carrying types a Z) c. Thisbell-cranktype-bar is pivoted to a vibrating or oscillating support. A.These supports are set in the arc of a circle and are pivoted to fixedsupports h. The supports A are provided with stop projections g.

A is one of a series of key levers fulcruined at q, the rear ends ofwhich are severally connected to and operate the type-levers by means ofrods 6.

y is a stop-piece formed into steps 1, 2, and 3, having a verticalmovement imparted to it by suitable mechanism. .(Not shown.) When thestop y is in the position shown and the key-lever is depressed, theprojection g is pressed against the step 1, and the type-bar OD, bymeans of the rod 6, is thrown down to print the letter a. When the stopy is raised to the second posltion,the projection g is thrown forwardagainst the step 2 and the letter I) is printed, and so on.

My present form. of type-writer is designed to print directly from thetypes without the use of an inkingribbon, and in the drawing I haveillustrated one means of inking the types for this purpose, but othermeans of accomplishing the same result substantially may be employedwithout departing from the spirit or scope of my invention, the essenceof the invention consisting of a movable pad operated by suitablemechanism, which causes it at intervals to approach and recede from theface of the printingiype to thoroughly ink it, and then to retire to aposition where it will not obstruct the operation of printing.

In the annexed drawing, 0 is a pad or roller, which may be supplied withink by intermediate rollers or in any well known manner. Itis connectedby the bent rod 0 with a rotary cam, H, against which the end of the rodG bears, which rod is pivoted to the frame at s, and is actuated byakeylever arm, D. If desirable, this lever may be connected to the key,by means of which spacing between words is accomplished, or to a keycontrolling any other operative partof the machine. Each time the key Dis depressed the end of the lever G, riding up the cam H, causes theinking roller or pad to pass over or be pressed against the face of theprintingtypes, and when the key Dis released the force of the spring Z,connected to said cam, causes the inking roller to return to theposition illustrated in the drawing.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. In a type-writing machine, the types thereof combined with an inkingpad and a key-lever by which it is operated, substantially as described.

2. In a type-writing machine, the types thereof combined with aninking-pad con-' nected to and operated by a vibrating bar, 0, for thepurpose of pressing said pad against the face of the typeintermittently, substantially as described.

3. Ina type-writing machine,an.inking-pad, 0, combined with a revolvingcam, H, provided with a spring, connecting-rod O, and a key-lever,substantially as described.

BYRON A. BROOKS.
